Answer:
27.2%
Step-by-step explanation:
multiply 0.272 by 100
Answer:
Step-by-step explanation:
For the spring mass system
my"+by'+ky=0
The system is said to be critically damped if 
Here b is coefficient of friction
m is the mass of system
And k is spring constant
We have given m = 2 kg , k =1
So 
So the coefficient of friction is 
We define the variables first:
x = number of male cousins
y = number of females cousins
We write the system of equations:
x + y = 9
x = y-2
We solve the system:
Equation 1:
x + y = 9
(y-2) + y = 9
2y-2 = 9
y = 11/2 = 5.5
Equation 2:
x = 5.5-2
x = 3.5
Answer:
Although physically it does not make sense, mathematically the answer is:
number of male cousins = 3.5
number of females cousins = 5.5
If I'm not mistaken, then the answer must be the last option.
Hope I understood correctly for your sake.
